One in 20 private renters claim to have suffered carbon monoxide (CO) poisoning in their home in the past five years, according to new research for Shelter Scotland and Scottish Gas.
The Scotsman reported the survey found about 5% of those renting from a private landlord had been affected.
Meanwhile, about two-fifths (43%) of renters said their landlord or letting agent had failed to carry out gas safety checks in the past five years, with 7% of tenants stating they had experienced a gas leak in this period.
Shelter Scotland has joined forces with Scottish Gas in a bid to improve housing in the private rental sector.
A total of 1,387 people privately renting their home were questioned for the research, which was carried out by YouGov.
